`nLvvIN rr. RIDDER, or CHICAGO, ILLINOIS, AssIeNOn TO LINK-BELT COMPANY, or CHICAGO, ILLINOIs, A COnPOanTrON or ILLINOIs CAR Dmvrr Q.Application led January 31, 1927. Serial No. 164,771.

This invention relates to a car dump. It includes generally a rolling frame intoV which the car may be moved. rlhe frame is mounted on a track so that it is bodily rolled. It

y, is provided With mechanism so that as it is rolled, the car is automatically clamped into position Within the frame. One object of the invention is to provide With such an apparatus means for moving the car and frame w laterally as they are tipped. Another object of the invention is to provide means whereby the car and frame aretimed norf mally under the influence of gravity Vto ret-urn to the original upright position When 15 free to do so. Other objects Will appear throughout the specifications and claims.

The invention is illustrated more or less diagrammatically in the accompanying drawings, Wherein Figure 1 is an end elevation. l Figure. 2 is a vertical section on line 2f-2 of Figure l on an enlarged scale.

Figure 3 is an enlarged fragmentary end elevation With parts in section.

Figure 4 is a vertical section taken on line 4 4: of Figure 3.

Like parts are indicated by like characters throughout.

A, A are beams carrying tracks A1, A1.

5.a These tracks are preferably double as shown.

One end of the beams A is carried on a foundation A2.- It is further supported at its other end and adjacent its center on columns A3, A3 Which are supported on foundations A4.

B, B are generally circular members provided each on its periphery With a track portion B1, having preferably a raised central portion B2. The members B are joined by io reenforcing and strengthening parts Which may be of any suitable construction. B3 is a boX shape frame in which counteriveights and certain clamp controlling mechanisms may be mounted. These are not shown in 4.5 greater detail as their particular construction forms no part of the present invention.

O is a car supporting frame having upon it tracks O1 O1. Beneath the frame and attached to Vitfare a plurality of Contact or ,59 bearing 'Port-ions, G2. G3 C3 are Wheels mounted for rotation in thek members B. The portions C2 are in Contact With the rollers C3 and thus the frame O is supported upon the rollers and is adapted to have limited lateral movement.

D is an opening in each of the members B and Within this opening the car frame C is mounted. 1D1 is a car contacting and material controlling Wall. It is preferably formed of Wood and the car is moved over against it during the tipping operation.

D2 D2 are clamps. Their details of construction form no particular part of the presentinvention and Will therefore not be fully described. It is sutlicient to say that When a car is run upon the dumper, these clamps automatically or otherwise hold the car in position so that dumping may be properly carried out.

E indicates a car in the 'dumpen F is a hoisting mechanism of any suitable type. F1 F1 are main dumping cables and are joined to the members B at F2. Each of these cables passes over a sheave F3. F4 F4 are slip preventing cables. Each is attached at one end to one of the members B as at F5 and at its other end to the frame-Work A as at F6. F7 F7 are additional slip preventing cables. Each is attached at one end to one of the members B as at F8 and at the other end each is attached to a member secured to the foundation A2 as at F9. The cables F4 and F7 serve to prevent slipping or skidding of the rolling assembly in either direction so that When the member is rotated toward the dumping position along the track, it Will rotate positively.

G is a hopper having an open upper receiving portion and a restricted downwardly discharging portion G1. G2 is a closure for the 'discharging portion movably mounted upon supports G3. j

At one or more points on the frame C and preferably adjacent each end, there is mounted a roller H.

J is a controlling lever mounted for rotation at J1 in a bearing J 2 which is supported upon the foundation A2. When the dumper is in the upright or undumped position as Shown in full lines in Figures l, 3, and 1i pan eov . of the lever K.

tieularly, this lever J is in contact with the roller H and prevents lateral movement of the frame C. J* and J 5 are stops for the lever J.

K is a bearing supported upon the foundation A?. K1 is a shaft journaled in the bearing and having fixed upon it a lever K2. K3 is a connecting link joined at one end to the outer end of the lever K2 and at the other and to" the extension J 3 of the lever J. K4 is a second lever fixed on the shaft K1 and carrying adjacent its outer end an adj ustably mounte counterweight K5. Ke is a portion It carries in its outer end a roller K which normally bears against the trackportion B1.

L is a shaft or rod extending through the carrier frame and also extending through a portion of the car supporting frame. L1 is y a sprin positioned by the member L and Lz eet " tion a car is moved upon it.

.takes is' a' oo ar positioned also onl the member L conftaetig at one end with the frame C and at the other with the spring L1.

While I have shown an operative device, still it will be obvious that many changes might be made in the size, shape and arrangexne'ht of parts without departing materially from the spirit of my invention and I wish, therefore, that my showing be taken as in a si'lsediagrammatic.

The use and operation of the invention are as foilows:

The damper is shown in the loading posi# tion in Figure 1 in full lines. In that posi- TheVV hoisting l'eohailism is then put in operation and the hoisting l cables are drawn in causing ythe damper fra-me to roll laterally along the tricks. As this movement commences, the clamps, preferably automatically operated, come into position to engage and hold the car inopr position.

i s t dumper rolls to the left as shown particularly in Figure 1 and in detail in Figltr'e, the roller K is in engagement with the track on the member B. As the dumping frame assembly rolls itl tends to nieve away from the roller K. As this movement continues the lever K and the counterweight K5 tends to rotatedownwardly andl thus through tle levers K andthe connecting links K3 and the levers J the framework C is permitted to move laterally at first under the influence of the s ring Ll which is normally under comwhen the parts are in the position sli'tnin Figure 1. Thus as theresult of the r lling of the car carrying assembly the car 'me C is freed for lat-eral movement. the movement occurring initially as a result of the ex ansion of the spring. This action A e because the downward movement dfthele't'er K* through the linkage above litiitoetl causes they lever J to move to the l'et asslio'wn in Figures'l and 3 aiid'thus to peiitthe fratrie C to be moved to the left by the sprin Thus as the dumping assembly is rolled laterally the car frame is moved automatically laterally first by the spring and then by the influence of gravity as the dumping movement is continued until the car lies against the part D1.

As the dumping is continued, the car and the frame assembly which holds it are rolled laterally and when the car is over the receiving hopper the tipping movement has progresse( suliicient'l'y to cause some of the contents of the car to be discharged. The tipping movement may be continued until the car is practically upside down. W'hen the dump is complete t e dumping assembly is rotated in the reverse direction and moves backward again to the original position. As it reaches the original position, the lever assembly above described operates againv and again the levers J' engage the rollers H and regulate the movement and position of the frame C.

During the rolling tipping movement, the

cables F* wind about themembers B and prevent their slipping. This is particularly important where the tracks are at anl incline as shown inthe resent construction and where there is a tendency for the rotating frame assembly to slip or skid down hill while the hoisting mechanism is rolling it uphill. When the car carrying assembly has rolled away from the filling position, so'that the lever J is outV of contact with the roller H, the movement of the lever J to the left, as shown in Figure 3 is'limited by the stops J and J 5. The counterweig'ht K5 tends tomovc the lever J always to the left but as soon as the adjustable stop'J* has' contacted the fixed stop J 5, further movement in that direction is prevented.

The members F8 on each of the members B, in addition to their other functions, serve as stops to limit the car carrying assembly in the dumping direction. This is shown in the dotted line position in Figure l` in which t-he member FB is in contact with the member F10. Similar stopA members F12 are also mounted on the members B and they contact the stop members Fu which are mounted on the foundation member A2 when the car carrying assembly is in the upright or loading position as shown in full lines in Figure 1.
